AMP MODELS:CleanInspired by* the Eden Traveler, this model is all about clean, funk and fusion bass tone. It’ll give you all the warm lows and punchy highs you need

R&BInspired by* a '68 B-15 Flip Top, this model is a tribute to those late 60’s and early 70’s clean fat bass tones. It is the kind of tone you hear on most Motown recordings, as played by a pioneering young bassist, James Jamerson.

RockThis model is inspired by* the ’74 Ampeg® SVT® which has appeared on innumerable recordings and arena stages worldwide. Now, all the tone of the head and 300-pound behemoth 8x10 cab is available without having to lookup a chiropractor.

BritBased on a ’68 Marshall® Super Bass, this model delivers the kind of overdriven bass sounds brought to us by late ‘60s British rock pioneers like Cream and The Who.

GrindAs the name would suggest, this is for modern rock loversAlice in Chains to Mudvayne and Rage Against The Machine. Based on* a distorted SansAmp PSA-1 into an SVT® with a direct clean bass signal mixed in, this model gives you that angry, clear and punchy aggression that cuts through the mix and takes your sound to DEFCON 1.

CompressorThis pro LA-2A®-style compressor is ideal for every bass player and particularly useful for the ones who play with their fingersachieve a smooth and consistent signal at any volume.

Envelope filterBased on* a Q-Tron, this is the baddest envelope filter on the planet. This effect can be heard on tons of major funk and rock tunes.

OctaverBased on* the EBS® OctaBass®, this effect produces a single note one octave below the note you’re playing to add a powerful new vibe to your sound.

ChorusBased on* the much loved T.C. Electronic® Chorus. This is the most transparent, smooth and expressive chorus ever built for bassand using it won’t reduce your low end. It’s especially beautiful with fretless basses.

SynthSitting at the back of the model knob is this secret weapon that turns LowDown into a ’70s classic bass synth. From funk to modern rock, this fully adjustable synth delivers incredible tones while tracking every dynamic move you make!
